Subject: [PATCH] Create CMakeLibTests output dir for Xcode

Xcode 2.x forgets to create the target output directory before linking
the individual architecture pieces of a universal binary for the target
CMakeLibTests.  Then it passes the directory to -L and -F options when
linking the and warns that the directory does not exist.  We work around
the problem by using a pre-build rule on the target to create the output
directory.
